The Azden AZDEN-SMX-10 is a compact, directional stereo shotgun microphone specifically engineered for use with DSLR cameras, mirrorless cameras, and camcorders to significantly improve onboard audio capture. It is designed to mount directly onto the camera's hot shoe, providing a convenient, integrated solution that avoids the clutter and complexity of separate recorders and booms for run-and-gun videography, documentary work, and event coverage. The microphone employs a dual-capsule stereo array housed within an interference tube, allowing it to capture a realistic stereo image with a focused pickup pattern that emphasizes sound from the front while reducing ambient noise from the sides and rear. This directionality helps isolate the subject's voice or primary audio source, delivering clearer, more intelligible audio compared to a camera's built-in omnidirectional microphones.

The SMX-10 features a versatile three-position switch that allows the user to select between different polar patterns to suit various recording scenarios: a focused "Shotgun" (supercardioid) mode for maximum front-axis rejection, a "Stereo" mode that engages both capsules for a natural left-right stereo image, and a "Medium Angle" mode that provides a wider pickup pattern for capturing more ambient sound or group conversations. The microphone is powered either by a single AA battery or via phantom power supplied through the camera's 3.5mm mic input if supported, offering flexibility in the field. It includes a built-in shock mount to minimize handling noise transmitted through the camera body, and a foam windscreen to reduce wind buffeting during outdoor use—both critical accessories for achieving clean audio in mobile production.

Output is via a 3.5mm TRS mini-plug that connects directly to the camera's microphone input, and the microphone includes an output level control for optimal gain staging to prevent distortion. Its lightweight, balanced design ensures it remains stable on the camera hot shoe without tipping. The Azden SMX-10 addresses the common audio limitations of DSLR filmmaking by providing an easy-to-use, directional stereo microphone that dramatically enhances production value without requiring external recorders or complex setups, making it an essential tool for solo shooters and videographers seeking professional-grade audio directly into their camera.
